2 Claims. (Cl. 160-101) This invention relates to a window constructionand more particularly to a window construction having builtin storm andscreen protection.

An object of this invention is to provide a window construction in whichstorm and screen inserts are removably built into the structure andbetween a pair of sliding window members and the inserts are concealedfrom both inside and outside of the window.

Another object of the invention is to provide a doublehung windowconstruction including upper and lower window sashes which are arrangedwith a space between their meeting rails so that a pair of verticallydisposed inserts may be placed therebetween to provide the desired stormor screen protection depending upon the structure carried by theinserts.

A further object of the invention is to provide a window construction asdened in the preceding paragraph wherein the vertically disposed insertsare arranged in abutting relation in vertically disposed channelspositioned between the upper and lower window sash with one of thesashes positioned to form part of said channels and being removable toenable placement and removal of the inserts in the channels.

A further object of the invention is to provide a window constructionincluding a window sash which is removably mounted in the window framingby means which include a friction strip extending along one sash stilein sliding engagement with the adjacent window jamb, and means carriedby the sash stile for moving the friction strip to a position to permitwithdrawal of the window sash and to additionally vary the frictionengagement between the friction strip and the jamb to provide propercounterbalance of the sash.

The objects of the invention generally set forth together with otherancillary advantages are attained by the construction and arrangementshown by way of illustration in the accompanying drawing, in which:

Fig. 1 is a vertical elevation of a window construction including thewindow framing, looking from the inside out, and with the lower sashslightly raised;

The scope of the invention will be pointed out inthe appended claims.

The window construction as shown in Figs. 1-3 comprises a lower windowsash 1 and an upper window sash 2 having spaced apart meeting rails 3and 4, respectively. The upper Window sash 2 has Stiles 5 and 6 at itssides. The stile 6 has vertically extending grooves 7 which slidablyengage projectio-ns 8 formed in a block 9 forming part of one side jamb.The groove 7 and projections 8 constitute coacting means for slidablyconfining the sash stile 6. The sash stile 5 carries a verticallyextending friction strip 10 Which is generally U shaped and has one leg11 embedded in the stile 5 as by providing a vertically extending sawcuttherein. The friction strip is arranged to be somewhat exible and may bemade of aluminum or other suitable material. A base part 12 of thefriction strip 10 is arranged to slidably engage a guide surface `13formed in a block 14 forming part of the side jamb, The guide surface 13tapers inwardly away from the sash stile 5. The base part 12 of thefriction strip and the block 14 have slidably interengaged parts, asindicated at 15, to define coacting means for slidably confining thesash stile 5. Another leg 15a of the friction strip extends verticallyalong the front of the sash stile 5 for a` purpose more fully set forthhereinafter.

The lower Window sash 1 has stiles 16 and 17 at the side thereof, andthe stile 17 is slidably confined to a vertically extending side jambsection 18 by coacting means, indicated at 19, comprising interengaginggrooves in the stile 17 and projections on the jamb section 18. Thestile 16 carries a friction strip 20 generally similar to that carriedby the upper window sash 2 and has a leg 21 embedded in the stile 16`and a base part 22 at an oblique angle to the leg 21 which slidablyengages a surface 23 formed in the side jamb member 24 and which tapersinwardly away from the sash stile `16. Another leg 23 of the frictionstrip 20 extends vertically along the front of the stile 16, and theconnection thereof to the base part 22 of the friction strip forms, witha notch 26 in the side jamb member 23, coacting means for slidablyconfining the stile 16.

As shown in Fig. 3, the meeting rails 3 and 4 are spaced apart toprovide a space through which a pair of vertically displaced inserts 27`and 28 may extend in abutting relation. These inserts may comprise asurround frame formed of a U-shaped, metal channel and receive panels ofglass, such as indicated at 29, or a section of screen, such asindicated at 30, each of which may be secured to the surround frame bybeing embedded in suitable material.

The right-hand sides of these inserts 27 and 28. looking at Fig. 2, areconfined in a channel extending vertically between the upper and lowerwindow sashes. This channel is defined by the jamb sections 18 and 9 anda base jamb section 31 to which the jamb sections 9 and 18 are secured,the jamb sections 9, 18 and 31 forming a side jamb.

The left-hand sides of the inserts 27 and 28, looking at Fig. 2, areconfined in the space between the upper and lower window sashes at oneof their ,faces by the jamb sections 14 and 24 which comprise a sidejamb and forming in part a channel which is completed by the stile 16 ofthe lower window sash 1.

As in conventional window construction, there may be a sill 32 fromwhich the side jambs extend upwardly, and exterior trim members 33 and34 also extend upwardly from the sill and partially over blind stopmembers 35 and 36 which engage and partially enclose the outer weatherfaces of theupper Window sash stiles 5 and 6. The other structuresurrounding the window construction may include a conventional wallconstruction.

`It will be seen trom the foregoing that a pair of slidH -able windowmembers have been provided with a space between their meeting rails sothat a pair of vertically disposed inserts maybe disposed therebetweenin abutting relation with each other, and the inserts are coniined by awindow sash and cooperating side jamb structure.

In order to remove the lower window sash 1 so as to give access to theinserts 27 and 28 for removal thereof or to permit insertion of theinserts, the mechanism as shown particularly inFigs. 4 and 5 isprovided. The friction strip is provided vwith a pair of verticallyspaced, elliptical openings 40 and 41, as shown in Fig. 1. Associatedwitheach of these openings is a rotatable plugv42 rotatably embedded inan opening in the stile 16. This plug has anl exposed flange 43 which iscircular so that portions thereof lie behind the friction strip" inorder to confine the plug in the stile. Extending outwardly from theflange 43 is a T-shaped projection 44including a pair of legs 45 .and 46of equal length and a cam section 47 having a slightly greater lengththan either of the legs 45 or 46. With this co-nstruction, rotation ofthe plug 42 in a clockwise direc'- tion, looking at Fig. 4, will carrythe cam section 47 in a clockwise direction so as to ride against theedge of the non-circular opening 40 and function to pull the frictionstrip 20 away from the jamb surface 23 and clear of the notch 26 formedin the side jamb so that the edge of the window including sash stileg16Vmay be moved inwardly a distance suicient to then permit release of thecoacting coniining means associated with the stile 17. The cam section`47 may be moved back generally to the position shown in Fig. 4 afterthe window sash is again put in place so as to return the friction strip20 into sliding engagement with thel jamb surface 23 and behind the jambnotch 26. The rotatable plug `42 may also be slightly adjusted in eitherdirection of rotation so as to vary the friction engagement of thefriction strip 20 lwith the surface 23 in order to properlycounterbalance the sash. I

A suitable key for operating the plug 42 is shown in Fig. 6 wherein adisc 4S has a handle 49 secured thereto, and the disc 4S carries fourraised lugs 50 which may be placed against and interfitted with theraised, T-shaped projection 44 in order to facilitate turning of thelug.l

The structure shown in Figs. 4 and 5 is yalso utilized with lthefriction strip 10 associated with the upper window sash 5 to enableremoval of the upper sash, and the openings in the friction strip 10 areshown at 51 and S2 in the upper sash 2. j

The structure for rendering the sashes removable, as well as adjustingthe sliding action thereof with a minimum of force, renders it extremelysimple for a person to remove or replace a window sash for purposes ofcleaning the window glass or handling inserts 27 and 28.

It will be obvious that either screen or storm glass may be `carried bythe inserts 27 and 2S, depending upon the season of the year, and it ispossible to always have oneV insert provided with glass, as shown at 29,and to have two dierent, alternatively usable inserts at 27, one ofwhich may have screen material, and the other glass.

I claim:
